Description

Technical Field

[0001] The present invention relates to the technical field of deep drawing and spinning with diameter expansion, and particularly relates to a high-precision metal deep drawing and spinning device based on a new transfer die technology. Background Art

[0002] Deep drawing and spinning is a metal forming process in which a metal sheet or a hollow blank is fixed on a rotating mandrel, and a pressure is applied to the blank by a spinning wheel (or a spinning tool), causing the blank to gradually conform to the shape of the mandrel and undergo plastic deformation. During the deep drawing and spinning process, the main deformation modes of the blank are stretching and thinning. Deep drawing and spinning is applicable to various processing methods, including deep drawing and spinning with diameter expansion.

[0003] Deep drawing and spinning with diameter expansion mainly applies a pressure to the inner wall of a rotating cylindrical metal blank by a spinning tool, causing continuous local plastic deformation of the inner wall of the cylinder, so as to achieve the purpose of diameter expansion. During this process, the blank is tightly fixed on the mandrel of the spinning machine, and the spinning wheel acts on the surface according to a certain trajectory and pressure. For example, a cylindrical blank is fixed on the mandrel, and the spinning wheel gradually extrudes along the inner wall of the cylinder, causing the edge of the thin plate to expand outwards, just like changing a small-diameter cylinder into a large-diameter cylinder in this way.

[0004] Although the existing deep drawing and spinning devices can effectively perform diameter expansion treatment on the blank, there are still the following problems: Deep drawing and spinning with diameter expansion is to repeatedly process the inner wall for multiple times. After the spinning wheel spins the inner wall of the blank for the first time, the staff needs to manually clean the waste generated during the spinning process of the inner wall of the blank, and it needs to be cleaned every time it is spun, so as to ensure the spinning quality and prevent the waste residue from scratching the inner wall of the blank. The multiple cleanings seriously affect the spinning efficiency.

[0005] Therefore, it is necessary to design a spinning and stretching device that can continuously and evenly spray spinning oil on the inner wall of the blank when the spinning wheel spins the inner wall of the blank, and at the same time, directly clean the waste on the inner wall when the spinning wheel moves out of the inner wall of the blank after spinning the inner wall of the blank once, without the need for manual cleaning multiple times, effectively improving the spinning quality and efficiency. Summary of the Invention

[0006] In view of the problems in the prior art that it is impossible to continuously and evenly spray spinning oil on the inner wall of the blank and it is necessary to manually clean the waste in the inner wall of the blank every time the inner wall of the blank is spun, which affects the spinning quality and efficiency, a high-precision metal deep drawing and spinning device based on a new transfer die technology is proposed.

[0007] The present application provides a high-precision metal drawing and spinning device based on a new transfer die technology, and its purpose is as follows: by setting a cleaning component and a control component, when the first spinning wheel spins the inner wall of the blank, the control component tightens the nylon thread in the cleaning component, enabling the first spinning wheel to spin the inner wall of the blank normally. When the first spinning wheel processes one pass from the outside to the inside of the inner wall of the blank, during the process of the first spinning wheel moving from the inside to the outside, the control component releases the nylon thread, and the high-speed rotating conduction rod causes the nylon thread to unfold. The first spinning wheel sweeps out the waste generated during the one-pass spinning during the outward movement, directly completing the cleaning of the inner wall of the blank without manual participation, effectively improving the spinning efficiency. At the same time, an oiling component is arranged in front of the first spinning wheel, so that the oiling component oils the inner wall area of the blank in front before the first spinning wheel spins, ensuring that the inner wall of the blank is coated with spinning oil during processing, effectively improving the spinning quality.

[0032] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention will be made in conjunction with the accompanying drawings of the specification.

[0033] Example 1, refer to Figures 1-4 , which is the first embodiment of the present invention, provides a high-precision metal drawing and spinning device based on a new transfer molding technology, including a bottom plate 1, a mounting plate 2 fixedly installed at the upper end of the bottom plate 1, a spinning machine table 3 fixedly installed on the mounting plate 2, and further includes an operating unit installed on the spinning machine table 3. The operating unit includes a spinning component and a cleaning component installed on the spinning machine table 3.

[0034] The spinning component includes a sliding groove 4 opened on the spinning machine table 3, a sliding block 5 slidably installed in the sliding groove 4, an operating table 6 fixedly installed on the sliding block 5, a connecting plate 7 fixedly installed on the operating table 6, a cushion block 8 fixedly installed on the connecting plate 7, a conversion box 9 rotatably installed on the cushion block 8, a fixing plate 10 fixedly installed at the upper end of the conversion box 9, a servo motor 11 fixedly installed at the upper end of the fixing plate 10, a bearing plate one 12 and a bearing plate two 13 fixedly installed on the side wall of the conversion box 9, a rotating rod 14 rotatably installed on the bearing plate two 13, a spinning wheel two 15 fixedly installed at one end of the rotating rod 14, and an expanding and drawing component installed on the bearing plate one 12.

[0035] The end face of the sliding groove 4 is trapezoidal, the end face shape and size of the sliding block 5 are the same as those of the end face of the sliding groove 4, the conversion box 9 is rotatably installed on the cushion block 8, the driving end of the servo motor 11 is fixedly connected to the upper end of the conversion box 9, and a clamping component is installed on the mounting plate 2.

[0036] Refer to Figures 3-6 , the expanding and drawing component includes a conduction rod 16 rotatably installed on the bearing plate one 12, a spinning wheel one 17 fixedly installed on the outer wall of the conduction rod 16, and a plurality of driving motors are installed in the conversion box 9, and the plurality of driving motors respectively drive the corresponding rotating rod 14 and conduction rod 16. The clamping component includes a mounting groove opened on the mounting plate 2, an assembly ring 18 rotatably installed in the mounting groove, a clamping disc 19 rotatably installed on the inner ring of the assembly ring 18, and a mold cylinder 20 fixedly installed on the clamping disc 19 for placing the blank.

[0037] Specifically, the driving end of the servo motor 11 is fixedly connected to the conversion box 9, so that when the driving end of the servo motor 11 rotates, it can drive the conversion box 9 to rotate. A plurality of spinning tools are installed on the side wall of the conversion box 9, such as the first spinning wheel 17 and the second spinning wheel 15. The first spinning wheel 17 is used to expand the diameter of the inner wall of the blank by spinning, and the second spinning wheel 15 is used to perform deep drawing spinning on the outer wall of different blanks. By adjusting the angle of the conversion box 9 by the servo motor 11, the conversion box 9 can process different blanks with different spinning tools, effectively improving the applicability of the overall device (this is the prior art and will not be elaborated here). A control member (not shown in the figure) is installed on the spinning machine table 3, and the control member can control the operating table 6 to move freely in the horizontal direction to meet the position adjustment of the first spinning wheel 17 during diameter expansion by spinning (this is the prior art and will not be elaborated here again). The driving motor drives the corresponding rotating rod 14 or the conducting rod 16 to rotate at high speed through a transmission member (not shown in the figure) (this is the prior art and will not be elaborated here again).

[0038] The clamping assembly clamps and fixes one end of the blank through the clamping disc 19 therein. The blank is placed on the inner wall of the die cylinder 20 and fixed by the clamping disc 19. When the assembly ring 18 rotates, the blank is driven to rotate at high speed by the clamping disc 19 for diameter expansion by spinning operation. However, when the first spinning wheel 17 expands the diameter of the inner wall of the blank in the die cylinder 20, it is blocked by the cylinder wall on all sides. Therefore, it is difficult for the staff to spray the spinning oil on the inner wall of the blank at all times. And when the first spinning wheel 17 expands the diameter of the inner wall of the blank, to prevent the blank from deforming, multiple passes are usually used for operation, that is, when the first spinning wheel 17 spins the blank, it is from the outside to the inside. After the first spinning wheel 17 completes one pass of operation, the first spinning wheel 17 needs to be moved out, and the staff manually cleans the waste on the inner wall of the first spinning wheel 17 to prevent the waste from scratching the inner wall of the blank during the second pass. Manual processing is time-consuming and laborious, seriously affecting the quality and efficiency of the diameter expansion by spinning of the blank. For the above problems, the specific solutions are referred to the following embodiments.

[0039] Embodiment 2, refer to Figures 4-7 , which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the cleaning component includes a sliding sleeve 21 slidably installed on the outer wall of the conducting rod 16, a sector plate 22 fixedly installed on the outer wall of the sliding sleeve 21, a synchronous ring 23 fixedly installed on the outer wall of the sector plate 22, a plurality of linkage plates 24 fixedly installed on the side wall of the synchronous ring 23, a winding and unwinding ring 25 fixedly installed on the side wall of the plurality of linkage plates 24, a fixing ring 26 fixedly installed on the outer wall of the conducting rod 16, a plurality of nylon wires 27 evenly and equidistantly fixedly installed on the outer wall of the fixing ring 26 with the center of the fixing ring 26 as the axis, a control component is installed on the first bearing plate 12, and an oil application component is arranged inside the conducting rod 16.

[0040] The control component includes an electric rod 28 fixedly installed on the side wall of the first bearing plate 12, a push rod 29 fixedly installed at the telescopic end of the electric rod 28, and one end of the push rod 29 is fixedly connected to the side wall of the sector plate 22.

[0041] Specifically, during the spinning process of the blank, due to friction, a large number of small waste materials will be generated. If these waste materials are not processed in time, it will cause the waste materials to scratch the inner wall of the blank during the subsequent spinning process, affecting the appearance quality of the product. At the same time, the first spinning wheel 17 processes the inner wall of the blank in multiple passes. Therefore, every time the first spinning wheel 17 spins one pass, the staff needs to clean the waste materials on the inner wall, which affects the spinning efficiency.

[0042] The cleaning component is used to clean the waste materials on the inner wall of the blank after spinning and expanding the diameter. When the first spinning wheel 17 spins and expands the diameter of the inner wall of the blank, the electric rod 28 makes the push rod 29 extend through the telescopic end. During the extension process, the push rod 29 drives the synchronous ring 23 to move horizontally along the conduction rod 16 through the sector plate 22. During the movement of the synchronous ring 23, it drives the winding and unwinding ring 25 to move synchronously through the linkage plate 24. During the movement of the winding and unwinding ring 25, multiple nylon filaments 27 are in a tightened state (refer to Figure 5 ). The tightened nylon filaments 27 will not affect the normal spinning and diameter expansion of the first spinning wheel 17. After the first spinning wheel 17 spins and draws one pass, that is, when the first spinning wheel 17 is at the deepest position inside the blank, the electric rod 28 retracts the push rod 29 and synchronously drives the winding and unwinding ring 25 to retract. The winding and unwinding ring 25 releases the tightening of the multiple nylon filaments 27, causing the nylon filaments 27 to rotate synchronously and at high speed along with the conduction rod 16. The high-speed rotating nylon filaments 27 unfold under the action of centrifugal force. At this time, the first spinning wheel 17 is retracted, and the nylon filaments 27 move back in a circular shape along with the first spinning wheel 17. During the backward movement, the nylon filaments 27 can directly sweep the waste materials generated by one pass of spinning out of the inner wall of the blank (and after the high-speed rotating nylon filaments 27 along with the conduction rod 16 complete the cleaning of the inner wall of the blank, the high-speed rotating nylon filaments 27 can clean the waste materials inside the nylon filaments 27 through centrifugal force. Therefore, while the nylon filaments 27 can clean the inner wall waste materials, they do not need to be cleaned additionally and can be directly used next time), directly completing the cleaning of the blank, enabling the first spinning wheel 17 to directly perform the second pass without manual additional cleaning, effectively improving the spinning efficiency and quality.

[0043] The remaining structure is the same as that of Embodiment 1.

[0044] Embodiment 3, refer to Figures 7-8, which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the oiling assembly includes a conduction groove 30 opened inside the conduction rod 16, an extension cylinder 31 slidably installed at one end of the conduction rod 16, a nozzle 32 fixedly installed on the side wall of the extension cylinder 31, a cooling cylinder 33 fixedly installed on the outer wall of the conduction rod 16, and the cooling cylinder 33 is communicated with the conduction groove 30. A plurality of liquid outlet holes 34 are opened on the side wall of the cooling cylinder 33. A rotary joint 35 is rotatably installed at one end of the conduction rod 16 away from the extension cylinder 31. An oil pump 36 is fixedly installed on the side wall of the conversion box 9. An oil outlet pipe 37 is fixedly installed on the side wall of the oil pump 36. One end of the oil outlet pipe 37 is rotatably connected to one end of the rotary joint 35.

[0045] An oil inlet pipe 40 is installed on the side wall of the conversion box 9. An upper oil pipe is installed on the side wall of the oil pump 36. One end of the upper oil pipe is communicated with one end of the oil inlet pipe 40. A waste material box 38 is installed on the bottom plate 1. A discharge valve 39 is installed on the side wall of the waste material box 38.

[0046] Specifically, the conduction groove 30 in the conduction rod 16 is used for the flow of spinning oil. One end of the oil inlet pipe 40 is fixedly communicated with an oil barrel (not shown in the figure). The spinning oil in the oil barrel is pressed into the conduction groove 30 on the conduction rod 16 through the oil pump 36. After the spinning oil enters the conduction groove 30, the spinning oil is ejected through the cooling cylinder 33 and the nozzle 32 under the action of pressure. The spinning oil ejected by the nozzle 32 acts on the area to be spun, so that when the first spinning wheel 17 spins the inner wall area of the blank, it is ensured that there is enough spinning oil covering the area to be spun, ensuring the quality of spinning. The spinning oil ejected by the cooling cylinder 33 is used for cooling. When the first spinning wheel 17 finishes spinning and moves inward, the spinning oil ejected by the cooling cylinder 33 can directly cool the area after spinning, ensuring the quality of spinning. At the same time, the extension cylinder 31 is slidably installed at one end of the conduction rod 16, so that when the first spinning wheel 17 spins the innermost inner wall of the blank, the extension cylinder 31 can retract into the conduction rod 16 without affecting the normal spinning of the first spinning wheel 17.

[0047] The spinning oil and waste material cleaned by the nylon wire 27 directly flow into the waste material box 38 for collection. When the waste material in the waste material box 38 reaches a predetermined value, the staff can discharge and collect the waste material in the waste material box 38 by opening the discharge valve 39.

[0048] The remaining structures are the same as those in Embodiment 2.

[0049] Combining Embodiments 1-3, the working principle of the present invention is as follows: The staff places the blank to be spun in the mold cylinder 20, and the clamping disc 19 clamps the end of the blank. The first spinning wheel 17 is adjusted to the specified area through the servo motor 11, and the driving motor, the oil pump 36 and the control component are turned on.

[0050] In the initial state, the telescopic end of the electric rod 28 is in the extended state. The winding and unwinding ring 25 tightens multiple nylon wires 27. The driving motor drives the first rotating wheel 17 to rotate at a high speed. The control component controls the movement of the first rotating wheel 17 in the horizontal direction. The first rotating wheel 17 performs a spinning and diameter-expanding process on the inner wall of the blank from the outside to the inside. Since the nozzle 32 is in front of the first rotating wheel 17, the nozzle 32 rotates with the conduction rod 16 and sprays spinning oil on the area to be spun in the front. After spraying, the first rotating wheel 17 performs a spinning and diameter-expanding process on the inner wall. After the spinning is completed, the first rotating wheel 17 continues to move inside the inner wall of the blank. At this time, the spinning oil sprayed by the cooling cylinder 33 cools the spun area.

[0051] After the first rotating wheel 17 completes one pass of spinning on the inner wall of the blank, the first rotating wheel 17 is located at the innermost part of the inner wall of the blank. At this time, the telescopic end of the electric rod 28 is retracted, and then the winding and unwinding ring 25 is driven to retract through the sector plate 22 and the synchronous ring 23. The winding and unwinding ring 25 cancels the tightening of the nylon wires 27. At this time, the nylon wires 27 rotate at a high speed with the conduction rod 16 and unfold, so that the nylon wires 27 completely cover the inner wall of the blank. At this time, the first rotating wheel 17 moves outward and drives the nylon wires 27 to move synchronously. The moving nylon wires 27 sweep out the waste generated by one pass of spinning, completing the cleaning of the inner wall of the blank. After the first rotating wheel 17 completely extends, the telescopic end of the electric rod 28 is controlled to extend again, so that the nylon wires 27 are retracted again, and the position of the first rotating wheel 17 is controlled to perform a second pass of spinning on the inner wall of the blank, and the above operations are repeated until the spinning and diameter-expanding are completed.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
